I don't know really why (well, lack of information, surely) MacOS people continue to put themselves and their machines through the torture of building full Sagemath toolchain, whereas a considerable number of Homebrew packages can be used instead, including gfortran, gmp, yasm, NTL, etc etc etc.
I've played around with creating custom Homebrew formulae, here: https://github.com/dimpase/homebrew-science and have there (source code-only) formulae for flint and arb, something missing from the main Homebrew site. So you can do brew install dimpase/science/flint and brew install dimpase/science/arb to get up to date flint and arb built and installed, so that building Sage from source does not need these re-built. ------------------------- Needless to say, one can also install Conda, and installing Sage there will automatically install most of the Sage packages listed on https://trac.sagemath.org/ticket/27330 (so that they don't need to be built) And then building Sage from source at Conda "prompt" should be using them...
